Key facts
- Take naproxen with or just after a meal or snack.
- Take the lowest dose of naproxen for the shortest time to control your symptoms.
- The most common side effects of naproxen are confusion, headache, ringing in the ears, changes in vision, tiredness, drowsiness, dizziness and rashes.
- For strains and sprains, some doctors recommend waiting 48 hours before taking naproxen because it may slow down healing. If you're unsure, speak to a doctor.
- If you're taking naproxen for a long time or at risk of getting a stomach ulcer, your doctor may prescribe a medicine, such as omeprazole or lansoprazole, to protect your stomach.
